RetroBelt®'s 1964-75 GM lap and shoulder belt kit includes everything you will need to add a retractable seat belt system for two passengers to your classic 1967-68 Oldsmobile Delmont 88. Kits are available in eleven colors with color-matched stitching and retractors. The retractors hold 96 inches of webbing, with 39 inches of webbing outside for a total of over 11 feet of seat belt webbing. The buckle side is 27 inches long and is fully adjustable for maximum installation flexibility. Retractors have an advanced inertia design, which locks both top and bottom sections upon a sudden stop. Many GM vehicles in the early to late 1960’s were not equipped with seat belts. Adding seat belts to these vehicles is an invaluable investment in your vehicle and in your family’s safety. Advanced fabrication skills may be required to install anchor points; please consult with a professional installation specialist. Mounting hardware and a detailed installation manual are included. Price is per pair of seat belts for two passengers.
